Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a control method, device, and portable air conditioner. Background Technology

[0002] In portable air conditioners, excessively high compressor discharge temperatures can cause the following problems: abnormal compressor operation, overheating, overload, and in severe cases, damage to the compressor cylinder, resulting in safety hazards; in addition, it can reduce the gas delivery coefficient of the refrigeration system, increase shaft power, and long-term excessively high temperatures can lead to a decrease in lubricating oil viscosity, resulting in serious accidents such as cylinder wear and bearing failure, causing huge losses. Therefore, cooling the compressor cylinder is of great importance.

[0003] The larger the capacity of a portable air conditioner, the more condensate is produced by the evaporator during cooling. Current methods primarily use a water pump motor to drive a flywheel, splashing the condensate onto the condenser. This not only ensures timely condensate removal but also prevents the condenser from overheating. Based on this, a water pump can be used to extract the condensate to physically cool the compressor cylinder. However, when the ambient humidity is low, there is less condensate. In such cases, if the water pump is used to cool the compressor cylinder, the water pump motor will run idle, leading to excessively high condensing temperatures in the refrigeration system, resulting in poor cooling performance, high power consumption, and poor energy efficiency. Therefore, finding an optimal way to utilize condensate to achieve the best cooling combination between the compressor and condenser to ensure the cooling effect of the portable air conditioner is a problem that urgently needs to be solved.

[0023] Figure 3 This is a schematic diagram of the structure of a portable air conditioner provided in an embodiment of the present invention. Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] To facilitate understanding of this embodiment, the embodiments of the present invention will be described in detail below.

[0026] Example 1:

[0027] This invention provides a control method for a portable air conditioner. The portable air conditioner mainly includes a compressor, an evaporator, a condenser, a water tray, a water pump, and a water dispensing device. The evaporator is positioned above the condenser, and the compressor and condenser are positioned above the water tray. The specific structure of the portable air conditioner can be referenced from existing portable air conditioners, and will not be described in detail here.

[0028] like Figure 1 As shown, the control method for the aforementioned portable air conditioner includes the following steps:

[0029] Step S102: When the portable air conditioner is running in cooling mode, obtain the temperature parameters of the compressor;

[0030] Specifically, when the portable air conditioner is running in cooling mode, the evaporator produces condensate. The higher the ambient humidity, the more condensate is produced. Therefore, it is necessary to promptly remove the condensate from the drain pan to prevent it from overflowing. Simultaneously, to prevent damage to the compressor cylinder, it is necessary to obtain the compressor's temperature parameters in real-time or periodically to determine whether cooling of the compressor cylinder is required.

[0031] The temperature parameter refers to the compressor's cylinder temperature or exhaust temperature. This temperature parameter can be detected by a temperature sensor or a temperature sensor bulb. For example, the compressor's cylinder temperature can be detected by a temperature sensor or temperature sensor bulb installed on the cylinder, or the compressor's exhaust temperature can be detected by a temperature sensor or temperature sensor bulb installed at the compressor's exhaust port. This allows for the determination of whether the compressor's exhaust temperature is too high, and timely cooling of the compressor when it is too high, thus preventing damage to the compressor cylinder.

[0032] Step S104: If the temperature parameter is not less than the preset temperature threshold, obtain the water level of the condensate in the water receiving pan.

[0033] The preset temperature threshold is the temperature threshold corresponding to the temperature parameter, including the first temperature threshold corresponding to the cylinder block temperature and the second temperature threshold corresponding to the exhaust temperature. The first temperature threshold and the second temperature threshold may be the same or different, and can be set according to the actual situation.

[0034] Specifically, if the temperature parameter is the compressor cylinder temperature, it is determined whether the cylinder temperature is not less than a first temperature threshold. If so, it is determined that the compressor cylinder needs to be cooled. Similarly, if the temperature parameter is the compressor exhaust temperature, it is determined whether the exhaust temperature is not less than a second temperature threshold. If so, it is determined that the compressor cylinder needs to be cooled. Therefore, this embodiment of the invention utilizes the condensate generated by the evaporator to physically cool the compressor cylinder, which not only reduces the risk of the condensate in the drip tray reaching the full water alarm, but also achieves compressor cylinder cooling within the existing structure of portable air conditioners, reducing the control cost of compressor cylinder cooling.

[0035] Furthermore, since the water pumping device pumps water to cool the condenser, in low-humidity scenarios, if the compressor cylinder is still cooled by the condenser when there is little condenser, the water pumping motor in the water pumping device will run idle, resulting in a high temperature of the condenser in the refrigeration system. This will lead to poor cooling performance of the portable air conditioner. Therefore, in order to achieve optimal coordination between the compressor and condenser cooling, it is also necessary to detect the water level in the drip tray. The water level can be detected by a liquid level sensor or water level sensor, etc. The specific method of water level detection is not limited in this embodiment of the invention.

[0036] Step S106: Determine the target control method based on the water level and the preset height threshold;

[0037] The target control method is used to characterize the control of the water pump to draw condensate to cool the compressor cylinder; and / or the control of the water spraying device to spray condensate to cool the condenser. Therefore, based on the water level of the condensate in the drip tray, the water pump and / or the water spraying device are controlled respectively to maximize the use of condensate to physically cool the compressor cylinder and condenser. This not only achieves the optimal coordination of cooling of the compressor and condenser, but also ensures the cooling effect of the portable air conditioner, thereby ensuring the user's air conditioning comfort.

[0038] Step S108: Control the portable air conditioner to operate according to the target control mode.

[0039] After determining the target control method, the water pump and / or water dispensing device of the portable air conditioner are controlled to operate according to the target control method to maximize the use of condensate to physically cool the compressor cylinder and condenser, achieving optimal coordination of cooling of the compressor and condenser. This not only achieves optimal coordination of physical cooling of the compressor cylinder and condenser, but also ensures the cooling effect of the portable air conditioner; at the same time, it reduces the risk of the condensate in the drip tray reaching the full water alarm.

[0040] The control method for a portable air conditioner provided in this invention, when the portable air conditioner is running in cooling mode, if the temperature parameter of the compressor is not less than a preset temperature threshold, determines the target control mode based on the water level of the condensate in the drip tray, and controls the water pump and water dispensing device according to the target control mode, so as to maximize the use of condensate to physically cool the compressor cylinder and condenser. This not only achieves the optimal coordination of physical cooling of the compressor cylinder and condenser, but also improves the energy efficiency of the compressor and ensures the cooling effect of the portable air conditioner; at the same time, it also reduces the risk of the condensate in the drip tray reaching the full water alarm.

[0041] In one embodiment, the preset height thresholds include a first height threshold H1, a second height threshold H2, and a third height threshold H3, wherein the first height threshold > the second height threshold > the third height threshold, i.e., H1 > H2 > H3; wherein the value range of the first height threshold H1 is 30mm to 35mm, the value range of the second height threshold H2 is 20mm to 25mm, and the value range of the third height threshold H3 is 5mm to 10mm, and the specific values ​​of H1, H2, and H3 can be set according to the actual situation.

[0042] If the water level is not less than the first height threshold, the target control mode is determined to be the first control mode; wherein, in the first control mode, the water pump is controlled to extract condensate at high speed and spray it onto the cylinder of the compressor; at the same time, the water pumping device is controlled to pump condensate and spray it onto the condenser.

[0043] Specifically, when the water level height H≥H1, it indicates that there is a lot of condensate in the water receiving pan and the water level is deep. At this time, the target control mode is determined to be the first control mode. In the first control mode, the water pump is controlled to rapidly extract condensate at high speed and spray the condensate from top to bottom onto the compressor cylinder to quickly cool the compressor cylinder. At the same time, the water pumping device is also controlled to pump condensate and spray it onto the condenser to cool the condenser.

[0044] It should be noted that, in order to prevent misjudgment, when the water level height H≥H1 is detected, the judgment is continued for a preset time. The preset time is preferably 5s. If H≥H1 lasts for 5s, the target control mode is determined to be the first control mode. If it lasts for less than 5s, it is determined according to the case of H

[0045] Therefore, in the first control method, the water pump is controlled to quickly extract condensate, and at the same time, the water pumping device is controlled to pump water out of the condensate. This not only achieves the optimal coordination of physical cooling of the compressor cylinder and condenser, but also avoids the phenomenon of condensate overflowing in the water tray, reducing the risk of the water tray reaching the overflow alarm level.

[0046] In one implementation, if the water level is less than a first height threshold and not less than a second height threshold, the target control mode is determined to be the second control mode; wherein, in the second control mode, the water pump is controlled to draw condensate at a low speed and spray it onto the compressor cylinder; at the same time, the water pumping device is controlled to pump condensate and spray it onto the condenser.

[0047] Specifically, when the water level height H2≤H

[0048] ​​It should be noted that, to prevent misjudgment, when it is first detected that the water level height H2≤H<H1, the judgment is continued for a preset duration, where the preset duration is preferably 5s. For example, if H2≤H<H1 lasts for 5s, the target control mode is determined as the second control mode; if the duration is less than 5s, the determination is made according to the scenario of H≥H1 or H<H2.

[0049] Therefore, in the second control mode, the suction pump is controlled to extract condensed water at a constant slow speed, and at the same time, the water splashing device is controlled to splash the condensed water, so that when there is a small amount of condensed water in the water receiving tray, the condensed water is maximally utilized to physically cool the cylinder block of the compressor and the condenser, thereby realizing the optimal coordination of the physical cooling of the compressor cylinder block and the condenser, ensuring the refrigeration effect of the mobile air conditioner, and further guaranteeing the user's air conditioning comfort.

[0050] In one embodiment, if the water level height is less than the second height threshold and not less than the third height threshold, the target control mode is determined as the third control mode; wherein, in the third control mode, the water splashing device is controlled to splash the condensed water and spray it onto the condenser.

[0051] Specifically, when the water level height H3≤H<H2, it indicates that there is too little condensed water in the water receiving tray and the water level is too shallow. At this time, the target control mode is determined as the third control mode, and in the third control mode, only the water splashing device is controlled to splash the condensed water and spray it onto the condenser to cool the condenser. At this time, since there is too little condensed water, if the suction pump is still turned on to physically cool the compressor cylinder block, the water splashing motor of the water splashing device will idle, thereby reducing the refrigeration effect of the mobile air conditioner.

[0052] It should be noted that, to prevent misjudgment, when it is first detected that the water level height H3≤H<H2, the judgment is continued for a preset duration, where the preset duration is preferably 5s. For example, if H3≤H<H2 lasts for 5s, the target control mode is determined as the third control mode; if the duration is less than 5s, the determination is made according to the scenario of H≥H2 or H<H3.

[0053] Therefore, in the third control mode, the suction pump is controlled to stop running, and only the water splashing device is controlled to splash the condensed water, so as to preferentially ensure the refrigeration effect of the mobile air conditioner; meanwhile, in this process, the evaporator still generates condensed water. When the water level height H of the condensed water reaches the second height threshold H2, the suction pump is controlled to extract the condensed water to cool the compressor, avoiding damage to the cylinder block caused by the compressor being at a high temperature for a long time.

[0054] In one embodiment, if the water level height is less than the third height threshold, the target control mode is determined as the fourth control mode; wherein, in the fourth control mode, the suction pump and the water splashing device are controlled to stop running.

[0055] Specifically, when the water level H < H3, it indicates that there is very little condensate in the drip tray and the water level is very shallow. At this time, the target control mode is determined to be the fourth control mode. In the fourth control mode, both the water pump and the water pumping device are stopped. Since there is very little condensate at this time, if the water pumping device is still controlled to pump water to dissipate the condensate, it may cause the water pumping motor of the water pumping device to run idle, thereby reducing the cooling effect of the portable air conditioner. Therefore, it is necessary to control both the water pump and the water pumping device to stop running until the condensate water level reaches the third height threshold H3. Then, the water pump and / or water pumping device are controlled according to the water level to maximize the use of condensate to physically cool the compressor cylinder and condenser, thereby achieving the optimal coordination of physical cooling of the compressor cylinder and condenser.

[0056] It should be noted that when the water level height H < H3 is detected for the first time, the target control mode is determined to be the fourth control mode. This avoids the water pumping motor of the water pumping device from operating ineffectively when the condensate water level is extremely low, thus affecting the cooling effect of the portable air conditioner.

[0057] In one embodiment, the water-spraying device includes a water-spraying motor and a water-spraying flywheel connected to the shaft of the water-spraying motor and partially located in the water-receiving tray; the step of controlling the water-spraying device to spray water onto the condensate includes: controlling the water-spraying motor to rotate at a preset speed and driving the water-spraying flywheel to rotate, so that the condensate below the water-spraying flywheel is sprayed into water droplets and onto the condenser.

[0058] Specifically, when the water pump motor rotates at a preset speed, it drives the water pump flywheel to rotate. At this time, the condensate collected below the flywheel will be atomized into fine water droplets by the arc-shaped serrated blades of the flywheel and sprayed onto the condenser, such as onto the condenser fins, thereby quickly evaporating it from the high temperature of the condenser and achieving cooling of the condenser. The preset speed can be set according to actual conditions, and this embodiment of the invention does not limit the description in this regard.

[0059] In one embodiment, the method further includes: if the temperature parameter is less than a preset temperature threshold, controlling the water pumping device to pump water from the condensate and spray it onto the condenser to cool the condenser.

[0060] Specifically, when the temperature parameter is less than the preset temperature threshold, it means that the compressor cylinder does not need to be cooled. Therefore, only the water pumping device is controlled to pump water and spray it onto the condenser to cool the condenser. This not only cools the condenser but also prevents the water tray from overflowing, reducing the risk of the water tray reaching the overflow alarm level.

[0061] In summary, the control method for a portable air conditioner provided in this embodiment of the invention mainly includes the following processes:

[0062] (1) When the unit starts up and runs normally in cooling mode, the temperature parameters of the compressor are first checked; if the temperature parameters are less than the preset temperature threshold, the water pumping device is controlled to pump water to the condensate in order to cool the condenser.

[0063] (2) When the temperature parameter is not less than the preset temperature threshold, the water level height H of the condensate is obtained. If H≥H1 and lasts for 5s, the water pump is controlled to extract the condensate at high speed and spray the condensate from top to bottom onto the cylinder of the compressor to quickly cool the cylinder of the compressor. At the same time, the water pumping device is also controlled to pump the condensate and spray it onto the condenser to cool the condenser.

[0064] (3) As the water level H of the condensate decreases, when H < H1, if H < H1 is still satisfied within 5 seconds, then the water level is H2 ≤ H < H1. At this time, the water pump is controlled to slowly and uniformly extract the condensate at a low speed and spray the condensate from top to bottom onto the compressor cylinder to physically cool the compressor cylinder. At the same time, the water pumping device is also controlled to pump the condensate and spray it onto the condenser to cool the condenser. That is, as the water level of the condensate decreases, the pumping speed of the water pump is adjusted to avoid the water pumping motor from running ineffectively when the water level is low.

[0065] (4) As the water level H of the condensate drops, when H < H2, if H < H2 is still satisfied within 5s, then the water level is H3 ≤ H < H2. At this time, because there is too little condensate, only the water pumping device is controlled to pump water from the condensate and spray it onto the condenser to cool the condenser.

[0066] (5) As the water level H of the condensate continues to drop, when H < H3 for the first time, the water pump and water pumping device will stop running. This indicates that there is very little condensate at this time, thus avoiding the ineffective operation of the water pumping motor and ensuring the cooling effect of the portable air conditioner.

[0067] (6) As the water level of the condensate rises, the water pump and / or water dispensing device are re-controlled according to the water level to maximize the use of condensate to physically cool the compressor cylinder and condenser. This achieves the optimal coordination of physical cooling of the compressor cylinder and condenser, improves the energy efficiency of the compressor, and ensures the cooling effect of the portable air conditioner. At the same time, it also reduces the risk of the condensate in the drip tray reaching the full water alarm.

[0072] The second acquisition module 22 is used to acquire the water level of condensate in the water receiving pan if the temperature parameter is not less than a preset temperature threshold.

[0073] The determination module 23 is used to determine the target control mode based on the water level height and the preset height threshold; wherein, the target control mode is used to characterize the method of controlling the water pump to draw condensate to cool the cylinder of the compressor; and / or controlling the water spraying device to spray condensate to cool the condenser.
